## Model description

DistilBERT is a smaller, faster, cheaper version of BERT, achieved through knowledge distillation. It retains 97% of BERT’s language understanding while being 60% faster and smaller. This fine-tuned version of DistilBERT is trained to detect AI-generated text in paragraphs from the STEM domain.

Key characteristics:
- **Architecture**: Transformer-based model
- **Pre-training objective**: Masked Language Modeling (MLM)
- **Fine-tuning objective**: Binary classification (Human-written vs AI-generated)

## Intended uses & limitations

### Intended uses
- **AI Text Detection**: Identifying paragraphs in the STEM domain that are generated by AI versus those written by humans.
- **Educational Tools**: Assisting educators in detecting AI-generated content in academic submissions.
- **Research**: Analyzing the effectiveness of AI-generated content detection in STEM-related texts.

### Limitations
- **Domain Specificity**: The model is fine-tuned specifically on STEM paragraphs and may not perform as well on texts from other domains.
- **Generalization**: While the model is effective at detecting AI-generated text in STEM, it may not generalize well to other types of AI-generated content outside of its training data.
- **Biases**: The model may inherit biases present in the training data, which could affect its performance and fairness.

## Training and evaluation data

The model was fine-tuned on the "16K-trueparagraph-STEM" dataset, which consists of 16,000 paragraphs from various STEM domains. The dataset includes both human-written and AI-generated paragraphs to provide a balanced training set for the model.

### Dataset Details
- **Size**: 16,000 paragraphs
- **Sources**: Academic papers, research articles, and other STEM-related documents.
- **Balance**: Approximately 50% human-written paragraphs and 50% AI-generated paragraphs.

## Training procedure

### Preprocessing
- **Tokenization**: Texts were tokenized using the DistilBERT tokenizer.
- **Truncation/Padding**: All inputs were truncated or padded to a maximum length of 512 tokens.

### Hyperparameters
- **Optimizer**: AdamW
- **Learning Rate**: 5e-5
- **Batch Size**: 16
- **Number of Epochs**: 3

### Training
- **Loss Function**: Binary Cross-Entropy Loss
- **Evaluation Metrics**: Accuracy, Precision, Recall, F1-Score, ROC-AUC

### Hardware
- **Environment**: Training was conducted on a single NVIDIA Tesla V100 GPU.
- **Training Time**: Approximately 4 hours.

### Training hyperparameters

The following hyperparameters were used during training:
- learning_rate: 5e-05
